Ad Units
When you’ve created “Site” in your account you need to add “Ad Units” or “Ad Zones” - the entity in the site hierarchy that represents physical space on the actual website, the place where an ad should appear.
Under each “Site” a publisher can create one or several “Ad Units”. Ad units have own name, main size and a list of ad sizes that may be delivered within this ad unit. Ad units may have or may not have a connection with GAM ad units depending on site type. From the HTML code point of view, ad units are represented by a DIV that should be added into HTML page source code by the site owner. Each ad unit may be activated or de-activated in the wrapper, there is a switcher in UI. Publishers may add, remove ad units or edit parameters.
